Yiyiphi imilinganiselo yeBPD kwi-Your Pregnancy Ultrasound Means
Ububanzi beBiparietal (eyaziwa nangokuthi yi-BPD) ngenye yemilinganiselo emininzi ethathwa ngexesha lokukhulelwa kweenkqubo ze-ultrasound. Ingumlinganiselo wobubanzi phakathi kwesikhala sakho somntwana, ukusuka kwelinye ithambo leparietal ukuya kwelinye. I-BPD isetyenziselwa ukuqikelela ubunzima be-fetal kunye nobudala be-gestational.
Ziziphi iimpawu zeParietal?
Wonke umntu unamathambo amabini e-parietal-enye ngecala lasekhohlo lekhayi kunye nelinye kwicala lasekunene lekhayi.
Isithambo ngasinye separietal sifana nesitya esineqabileyo esineendawo ezimbini kunye namacala amane.
Ukufanekisa ukulinganisa ububanzi biparietal, cinga ukuthatha umtya kwaye ubeke esinye isiphelo saso phezulu kwindlebe yakho yangakwesokudla kunye nomnye ukuphela kwayo kwindlebe yakho yekhohlo, uvumele ukuphumla phezu kwentloko yakho. Ubude balo mtya bekunokukunika ingcamango enzima kakhulu yobuninzi biparietal. Xa umntwana wakho engaphakathi kwesibeleko sakho, uchwepheshe we-ultrasound uthatha lo mlinganiselo, ngelixa ekhangele umntwana wakho okhulayo kwikhompyutheni yekhomputha kunye nokusebenzisa izixhobo zokulinganisa zedijithali.
Njani kwaye xa i-Biparietal Diameter (BPD) iyalinganiswa
Umlinganiselo we-BPD udlalwa ngexesha le-ultrasounds ekukhulelweni. Abaninzi abasetyhini banokuvela kwindawo enye ukuya kweyesithathu (eyaziwa ngokuba yi-sonograms), ngokuqhelekileyo ngeveki engama-20. Abasetyhini abacatshangelwa ukuba basengozini enkulu banokufuna iimpawu ezingaphezulu.
Isilinganiselo seBPD sinceda kunye neminye imilinganiselo emithathu:
- Umlinganiselo wecala lomxholo
- Umlinganiselo wesisu esiswini
- Ubude besithambo lesifuba (ithambo lesithambo-ithambo elide kunabo bonke emzimbeni).
Ezi zintathu milinganiselo kunye kunye ncedisa ukuqikelela ubunzima be-fetal kunye nokuba kude kangakanani ukukhulelwa. Isilinganiselo se-BPD sinokunika kunye nogqirha wakho ingqiqo yokuba indlela yakho yokukhula kwengqondo ikhula ngayo.
Ukulinganisa ububanzi biparietal kukhula ukusuka kuma-2.4 centimitha kwiiveki ezingama-13 ukuya kuma-9.5 cm ubude xa umntwana ekhulile. Ugqirha wakho ufuna ukulinganisa i-BPD, kunye neminye imilinganiselo, ukuba ibe ngaphakathi kwinto ethathwa njengoluhlu oluqhelekileyo.
Ukuthatha isilinganiselo sokumitha kwebiparietal emva kwexesha lokukhulelwa akuthathwa njengokwethenjelwa ekuqaliseni iminyaka yobubele. Phakathi kweveki 12 kunye neveki 26 yokukhulelwa, i-BPD ihlala ichanekile ukuba iqikelele iminyaka yobudala kwisithuba seentsuku ezili-10 ukuya kwe-11. Nangona kunjalo, emva kweveki 26 yokukhulelwa, inokuthi ikhutshwe ziiiveki ezintathu. Ezinye iifundo zibonisa ukuba i-BPD iba nechanileyo kangangoko emva kweveki 20.
Xa i-BPD ingaphandle kweRange eliqhelekileyo
Ukuba iziphumo zentsana yakho zingaphandle kwebala eliqhelekileyo, ugqirha wakho unokufuna iimvavanyo ezingaphezulu ukuqinisekisa ukuba wena kunye nosana lwakho uphilile. Ngokomzekelo, ukuba imilinganiselo yengane yakho isecaleni elincinci, loo nto ingaba ngumqondiso wokunciphisa ukukhula kwe- intrauterine okanye ithetha ukuba intloko yakho yintsana iyaphaya kuneyona nto iqhelekileyo. Ngakolunye uhlangothi, ukuba imilinganiselo yengane yakho isecaleni elincinci, inokubonisa ukuba unenkinga yempilo, njengesifo sikashukela sesifo sikashukela.
